The Philippine National Coat of Arms

The Coat of Arms of the Philippines features the eight-rayed sun of the Philippines with each ray representing the eight provinces (Batangas, Bulacan, Cavite, Manila, Laguna, Nueva Ecija, Pampanga and Tarlac) which were placed under martial law by Governor-General Ramón Blanco during the Philippine Revolution, and the three five-pointed stars representing the three primary geographic regions of Luzon, Visayas, and Mindanao. In the blue field on the left side is the Eagle of the United States, and in the red field on the right is the Lion-Rampant of Spain, both representing colonial history. The design is very similar to the design briefly adopted by the Commonwealth of the Philippines in 1940.

The heraldic description from Republic Act No. 8491 of 1998 is as follows: Paleways of two (2) pieces, azure and gules; a chief argent studded with three (3) mullets equidistant from each other; and, in point of honor, ovoid argent over all the sun rayonnant with eight minor and lesser rays. Beneath shall be the scroll with the words "REPUBLIKA NG PILIPINAS," inscribed thereon.

The words on the scroll have undergone many changes since Philippine independence. From independence in 1946 until 1972, when President Ferdinand Marcos declared martial law, the scroll contained the words "REPUBLIC OF THE PHILIPPINES." From 1979 until the overthrow of Marcos in 1986, the scroll had the words "ISANG BANSA ISANG DIWA" ("One Nation, One Spirit") inscribed. After the overthrow of Marcos, the scroll changed to the current "REPUBLIKA NG PILIPINAS".

In 1998, with the approval of Republic Act No. 8491, the eagle and lion on the lower half of the shield have been removed. However, the modified arms are not in wide use, pending the ratification of the law by a national referendum called for that purpose, as mandated by the Philippine Constitution.
